What causes
railway noises?
1. Train motor noise
2. Aerodynamic noise
3. Wheel-rail noise or Rolling noise
Rolling noise caused from interaction between wheel and rail. The vibration and radiation of both wheel and rail will generate the rolling noise.
What is
Track Decay Rate (TDR)?
Track decay rate (TDR), in dB per m (dB/m), is widely adopted by the railway industry to indicates how far the vibration of certain frequency could travel along a rail [1]. Low TDR allows accumulation of vibration energy and leads to high rail vibration and excessive rail noise.
How to
mitigate railway noises?
1. Control at noise source. Such as
—Rail grinding
—Wheel reprofile
—Wheel damper
—Rail damper
2. Noise reduction at the transmission path. Such as
—Multi-plenum system
—Train skirt
—Noise wall barrier
—Noise enclosure
—Resilient base plate
—Floating slab track
3. Protection at the receiver
—Acoustic balcony
—Acoustic window
